NWebControl Class
In This Topic
NWebControl is the base class for all Nevron web controls. Its purpose is to implement the pluggable architecture for client-server communication technologies, which are represented by the NClientServerTechnology class.

Remarks
NWebControl delegates all steps from the web control's life-cycle, which are significant to the client-server communication, to an instance of a class, derived from the NClientServerTechnology class. This way, the AJAX client-server communication and the post-back client-server communication are implemented in separate classes, each class specialized per web control and client-server technology. E.g. Nevron Chart implements a NClientServerTechnology for AJAX and another NClientServerTechnology for post-back and Nevron Diagram implements another NClientServerTechnology for AJAX and another NClientServerTechnology for post-back. Within a single web control, different technologies can be switched dynamically at design time and at run-time, providing great flexibility in web control development.
